Smith, G R

Total domestic consumption of tungsten in primary end-use categories increased about 6% in 1990 compared with that of 1989. Demand for products other than carbides, such as steels, superalloys, and mill products, was moderately strong and accounted for approximately 4% of the increase. Most U.S. tungsten mines remained closed because of the persistently low prices for tungsten concentrate. Average prices for wolframite and scheelite concentrate decreased by 18% and 4%, respectively, in 1990, according to quotations published in Metal Bulletin (London). Based on a revised assessment of military requirements, the goal for the tungsten family group in the National Defense Stockpile was raised to a level essentially equal to the present inventory in the stockpile.
